Total revenue of $9.6 million in the second quarter of 2022, an increase of 35% over the second quarter of 2021 driven by strong growth in the cell therapy market; core business revenues grew 45% led by revenue from cell therapy customers which increased 61%, with drug discovery revenues growing by 4%.

Signed the Company's 17^th SPL agreement in July 2022; LG Chem licensed the use of MaxCyte's Flow Electroporation® ExPERT™ platform to advance cellular research and development of engineered cell-based therapies.

"We are pleased with these strong second quarter 2022 results, with 45% year-over-year core business revenue growth, highlighted by 61% growth in revenues from Cell Therapy customers. We remain encouraged by the ongoing growth of our SPL portfolio with the addition of LG Chem, our 17^th SPL partner, and second SPL agreement signed in 2022, as well as the continued progress of our existing partnerships. Importantly, our LG Chem partnership broadens the reach of our SPL portfolio into Asia," said Doug Doerfler, President and CEO of MaxCyte.

"Overall, our optimism about the potential for the development programs covered by our existing partners to generate growing revenue in both pre-clinical research and clinical progress remains high. Our ExPERT™ platform continues to be used to enable a broad range of cell types and approaches targeting a wide array of indications, and its adoption is increasing within the industry. We are making ongoing investments to drive revenue growth, support and expand the widening array of applications for our technology, while also strengthening our team and expanding our ability to support customers through in-house manufacturing and robust infrastructure.

Second Quarter 2022 Financial Results

Total revenue for the second quarter of 2022 was $9.6 million, compared to $7.1 million in the second quarter of 2021, representing growth of 35%.

Core business revenue was $9.6 million, including 61% revenue growth from cell therapy customers and 4% from drug discovery customers, compared to core business revenue of $6.6 million in the same period last year.

We did not have any material SPL Program-related revenue in the second quarter of 2022, as compared to $0.5 million in the second quarter of 2021.

Operating expenses for the second quarter of 2022 were $17.2 million, compared to operating expenses of $10.7 million in the second quarter of 2021. The overall increase in operating expenses was primarily driven by increased staff in field sales and science, manufacturing, and lab teams to support our customers' and partners' growth. The increase also included additional public company-related, stock-based compensation, and marketing expenses compared with the same period a year ago.

Second quarter 2022 net loss was $8.3 million compared to net loss of $4.4 million for the same period in 2021. EBITDA, a non-GAAP measure, was a loss of $8.2 million for the second quarter of 2022, compared to a loss of $4.1 million for the second quarter of the prior year.

The Company recognized $2.0 million of program-related revenue in the first half of 2022, as compared to $0.5 million in program-related revenue in the first half of 2021.

Gross profit for the first half of 2022 was $19.0 million (90% gross margin), compared to $12.1 million (89% gross margin) in the same period of the prior year.

Operating expenses for the first half of 2022 were $31.9 million, compared to operating expenses of $22.9 million in the first half of 2021. The overall increase in operating expenses was primarily driven by increased staff in field sales and science, manufacturing, and lab teams to support our customers' and partners' growth. The increase also included additional stock-based compensation, public company-related, and marketing expenses compared with the same period a year ago.

First half 2022 net loss was $12.3 million compared to net loss of $11.5 million for the same period in 2021. EBITDA was a loss of $11.9 million for the first half of 2022, compared to a loss of $10.5 million for the same period of the prior year.

Non-GAAP Financial Measures

This press release contains EBITDA, which is a non-GAAP measure defined as earnings, before interest, tax, depreciation and amortization. MaxCyte believes that EBITDA provides useful information to management and investors relating to its results of operations. The company's management uses this non-GAAP measure to compare the company's performance to that of prior periods for trend analyses, and for budgeting and planning purposes. The company believes that the use of EBITDA provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing the company's financial measures with other companies, many of which present similar non-GAAP financial measures to investors, and that it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making.

Management does not consider EBITDA in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of EBITDA is that it excludes significant expenses that are required by GAAP to be recorded in the company's financial statements. In order to compensate for these limitations, management presents EBITDA together with GAAP results. Non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. A reconciliation table of net loss, the most comparable GAAP financial measure, to EBITDA is included at the end of this release. MaxCyte urges investors to review the reconciliation and not to rely on any single financial measure to evaluate the company's business.
